The S99GLZM1222032 is a 12 mm bore, open-series linear plain bearing with an anodized aluminum housing and a J® polymer liner, designed for maintenance-free operation on hardened aluminum shafts with 8-16 RMS surface finish. It measures 22 mm outer diameter, 32 mm length, and 1.3 mm groove width, with a housing bore tolerance of +0.088/+0.030 mm. It operates continuously from -14°C to +90°C and intermittently up to +120°C. Load capacities are 215 kgf dynamic and 1510 kgf static at 0°, 142 kgf dynamic and 999 kgf static at 90°, and 54 kgf dynamic and 377 kgf static at 180°, relative to the 51 kgf/cm² dynamic and 356.8 kgf/cm² static pressure ratings. Securement is by set screws, not included.
A bearing is a device that reduces friction between moving components by preventing metal-to-metal contact while assisting components (shafts, axles, and wheels) to freely rotate around a fixed axis, cutting down on heat generation and the amount of energy that is consumed. By replacing sliding motion with low-friction rolling motion, the life of the rotating components is increased. A bearing also keeps the shaft in the proper position, providing support and alignment and transferring the axial or radial loads to the housing.
The types of bearings that we offer include rolling element bearings, which consist of both ball bearings and roller bearings.
Balls are utilized as the rolling element in ball bearings; a retainer holds the balls in place and allows them to freely rotate. The balls are kept inside channels cut in both the inner and outer races. Because there is no surface contact between the balls and races, precision ball bearings have a lower load capacity for their size than other bearings.
